Description

Technical Field

[0001] This utility model relates to the field of high-performance fiber preparation technology, specifically to an optimized structure for an electrospinning nozzle. Background Technology

[0002] High-performance fibers are a new generation of synthetic fibers developed by fiber science and engineering, possessing high strength, high modulus, and high-temperature resistance. High-performance fibers have unique properties not found in ordinary fibers and are mainly used in various fields of military and high-tech industries. The preparation of high-performance fibers refers to the process of processing raw materials into fiber materials with high strength, high modulus, and excellent properties through a series of technological steps. Electrospinning is a special form of electrostatic atomization of polymer fluids. In this process, the atomized material is not tiny droplets but polymer micro-jet streams that can travel considerable distances and eventually solidify into fibers. To improve the efficiency of high-performance fiber preparation, an electrospinning nozzle is needed; however, existing electrospinning nozzles still have the following shortcomings:

[0003] When using existing electrospinning nozzles, most of them are one-piece structures with only one nozzle, which easily affects production efficiency. Furthermore, it is inconvenient to disassemble and repair a single nozzle when it malfunctions, thus increasing production costs. This results in a decrease in the practicality and efficiency of electrospinning nozzles.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed an optimized structure for the electrostatic spinning nozzle. Utility Model Content

[0005] The purpose of this invention is to provide an optimized structure for an electrostatic spinning nozzle to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optimized structure for an electrostatic spinning nozzle, comprising a main housing and an installation assembly. A feed pipe is connected to the middle of the upper end of the main housing, and an installation assembly is provided at the lower end of the main housing. The installation assembly includes a discharge head body, an auxiliary thread, a threaded mounting groove, a threaded mounting ring, an installation mating groove, and a sealing rubber ring. An auxiliary thread is added to the upper outer end of the discharge head body, and a threaded mounting groove is opened at the upper inner end of the discharge head body, with a threaded mounting ring connected inside the threaded mounting groove. An installation mating groove is opened at the upper end of the discharge head body, with a sealing rubber ring provided inside the installation mating groove. A cleaning assembly is provided at the upper outer end of the main housing.

[0007] Furthermore, the auxiliary threads are equidistantly distributed on the upper part of the outer side of the discharge head body, and the auxiliary threads are fixedly connected to the discharge head body.

[0008] Furthermore, the internal dimensions of the threaded mounting groove are adapted to the external dimensions of the threaded mounting ring, and the threaded mounting ring is rotatably connected to the discharge head body through the threaded mounting groove.

[0009] Furthermore, the internal dimensions of the mounting groove are adapted to the external dimensions of the sealing rubber ring, and the sealing rubber ring is connected to the discharge head body through the mounting groove.

[0010] Furthermore, the cleaning assembly includes an air duct, an air pump, and a regulating valve. The air pump is installed in the middle of the air duct, and the regulating valve is installed at the upper end of the air duct.

[0011] Furthermore, the cleaning assembly also includes a storage chamber, an electrode body, and a heating element. The main housing has a storage chamber inside, and the electrode body is installed at the upper end of the storage chamber. A heating element is also added inside the main housing.

[0012] Furthermore, the regulating valve is perpendicular to the air supply pipe, and the regulating valve and the air supply pipe are fixedly connected by bolts.

[0013] Furthermore, the electrode body is embedded in the storage cavity, and the electrode body is fixedly connected to the storage cavity by bolts.

[0014] This invention provides an optimized structure for an electrostatic spinning nozzle, which has the following beneficial effects:

[0015] 1. This utility model, through the setting of the installation components, enables the discharge head body to be rotated and installed on the lower end of the main housing through the threaded installation groove and threaded installation ring when the electrostatic spinning nozzle is used in an optimized structure. The auxiliary thread improves the convenience of the rotation installation process. At the same time, the installation docking groove and sealing rubber ring improve the sealing performance after the discharge head body and the main housing are installed and docked. This allows the electrostatic spinning nozzle to replace the discharge head body with different nozzles according to production needs, improving the flexibility and dynamism of the electrostatic spinning nozzle during use.

[0016] 2. This utility model, through the setting of the cleaning component, enables the generation of a high-voltage electric field through the electrode body during the optimized use of the electrostatic spinning nozzle, causing the polymer solution or melt to become charged and form Taylor cones, ultimately forming fibers. The heating element set inside the main shell heats the material inside the storage chamber. By connecting the air duct to the upper part of the outside of the main shell, opening the regulating valve, and operating the air pump, the residual material inside the storage chamber can be effectively cleaned, thereby improving the maintenance efficiency of the electrostatic spinning nozzle and increasing the overall practicality and efficiency of the electrostatic spinning nozzle.

Detailed Implementation

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3As shown, an optimized structure for an electrostatic spinning nozzle includes a main housing 1 and a mounting assembly 3. A feed pipe 2 is connected to the middle of the upper end of the main housing 1, and the mounting assembly 3 is located at the lower end of the main housing 1. The mounting assembly 3 includes a discharge head body 301, an auxiliary thread 302, a threaded mounting groove 303, a threaded mounting ring 304, a mounting mating groove 305, and a sealing rubber ring 306. An auxiliary thread 302 is added to the upper outer surface of the discharge head body 301, and a threaded mounting groove 303 is formed inside the upper inner surface of the discharge head body 301. A threaded mounting groove 303 is internally connected to a threaded mounting ring 304. An installation mating groove 305 is provided at the upper end of the discharge head body 301, and a sealing rubber ring 306 is provided inside the installation mating groove 305. Auxiliary threads 302 are equidistantly distributed on the upper outer surface of the discharge head body 301, and are fixedly connected to the discharge head body 301. The internal dimensions of the threaded mounting groove 303 are adapted to the external dimensions of the threaded mounting ring 304, and the threaded mounting ring 304 is rotatably connected to the discharge head body 301 through the threaded mounting groove 303. Next, the internal dimensions of the mounting groove 305 are adapted to the external dimensions of the sealing rubber ring 306, and the sealing rubber ring 306 is connected to the discharge head body 301 through the mounting groove 305. The threaded mounting ring 304 is fixedly installed at the lower end of the main housing 1 by welding. The external dimensions of the threaded mounting ring 304 are adapted to the internal dimensions of the threaded mounting groove 303 opened inside the discharge head body 301. Thus, the discharge head body 301 is rotated and installed at the lower end of the main housing 1 through the threaded mounting groove 303 and the threaded mounting ring 304. The auxiliary thread 302 is used to improve the convenience of rotation installation. At the same time, the internal dimensions of the mounting groove 305 opened at the upper end of the discharge head body 301 are adapted to the external dimensions of the sealing rubber ring 306. Thus, the sealing performance of the discharge head body 301 after installation and docking with the main housing 1 is improved through the mounting groove 305 and the sealing rubber ring 306. At the same time, the discharge head body 301 with different nozzles can be replaced according to production needs, improving the flexibility and dynamism of the electrostatic spinning nozzle during use.

[0023] like Figures 1 to 3As shown, a cleaning assembly 4 is provided on the upper part of the main housing 1. The cleaning assembly 4 includes an air supply pipe 401, an air pump 402, and a regulating valve 403. The air pump 402 is installed in the middle of the air supply pipe 401, and the regulating valve 403 is provided at the upper end of the air supply pipe 401. The cleaning assembly 4 also includes a storage chamber 404, an electrode body 405, and a heating element 406. The storage chamber 404 is provided inside the main housing 1, and the electrode body 405 is installed at the upper end of the storage chamber 404. The heating element 406 is added inside the main housing 1. The regulating valve 403 is perpendicular to the air supply pipe 401 and is fixedly connected to the air supply pipe 401 by bolts. The electrode body 405 is embedded in the storage chamber 404. The electrode body 405 is fixedly connected to the storage chamber 404 by bolts. The electrode body 405 is fixedly installed inside the storage chamber 404 inside the main housing 1 by tightening the bolts. The electrode body 405 generates a high voltage electric field, which charges the polymer solution or melt and forms Taylor cones, eventually forming fibers. The heating element 406 installed inside the main housing 1 heats the material inside the storage chamber 404. The air pipe 401 is connected to the upper part of the outside of the main housing 1. The regulating valve 403 is opened and the air pump 402 is used to effectively clean the residual material inside the storage chamber 404, thereby improving the maintenance efficiency of the electrostatic spinning nozzle and increasing the overall practicality and efficiency of the electrostatic spinning nozzle.

[0024] In summary, this optimized electrospinning nozzle, during use, firstly delivers the material to be processed into the main housing 1 through the feed pipe 2. The discharge head body 301 is then rotatably mounted on the lower part of the main housing 1 via the threaded mounting groove 303 and threaded mounting ring 304. The auxiliary thread 302 further enhances the ease of rotational installation. Simultaneously, the mounting docking groove 305, in conjunction with the sealing rubber ring 306, improves the sealing performance after the discharge head body 301 is installed and docked with the main housing 1. This allows the electrospinning nozzle to be fitted with different nozzle types according to production needs. The main body 301 is then connected to the electrode body 405, which generates a high-voltage electric field to charge the polymer solution or melt and form Taylor cones, ultimately forming fibers. The heating element 406 inside the main housing 1 heats the material inside the storage chamber 404. The air duct 401 is connected to the upper part of the outside of the main housing 1. The regulating valve 403 is opened and the air pump 402 is used to effectively clean the residual material inside the storage chamber 404, thereby improving the maintenance efficiency of the electrostatic spinning nozzle and increasing the overall practicality and efficiency of the electrostatic spinning nozzle.
